Option to show the activity location on the picasso

Some users want to be able to show the location of each activity on the picasso. In many camps, the picasso is already too full, so this must be optional.

It should probably be a checkbox on the picasso pdf building block. This means that this option will be included in the print config, and must be repaired (default false) in repairPrintConfig as well.

Locate the picasso PDF building block, its print configuration, and repairPrintConfig; start by tracing how existing block options become PDF output. Add an optional location checkbox with a false default, ensure the setting is repaired, and verify that locations appear only when enabled.
